One global file system. Not a file server at every site.

Nasuni replaces branch-office Windows File Servers, DFS-R, and per-site backups with one cloud-native platform built on object storage. Every site, one console, no hardware to refresh, and real savings. See what they look like against your current footprint.

One file server isn’t the issue. A fleet of them is.

Most enterprises with Windows File Servers don’t have a Windows File Server problem. They have a branch-office sprawl problem: the same OS, replicated across every site, each with its own patches, backups, drives, and DFS-R quirks. Migration isn’t one project. It’s one per site. Nasuni replaces the fleet with a single global file system.

With Nasuni

One global file system. Every site, one console.

A fleet of physical boxes, one per site
  • Patch nothing. Nasuni Edge VMs are managed centrally and updated by Nasuni
  • No DFS-R. Global File Lock® and intelligent sync replace it natively
  • Backup is built in. Continuous File Versioning, every few minutes, unlimited retention
  • Capacity is cloud object storage, with no disks to fill and no procurement to chase
  • DR is part of the platform. Recover any site in 15 minutes, not days

A fleet of physical boxes, one per site

One global file system. Every site, one console.
  • Patch every server, every Tuesday, in every site
  • DFS-R replication that drifts, conflicts, and silently corrupts
  • Backup software you hope works, until restore day
  • Disks that fill, then fail, then refuse to procure on time
  • Standby DR servers idle 99% of the time, billed 100% of the time

Stop running a file infrastructure stack.
Run Nasuni instead.

Migrating to Nasuni isn’t replacing a Windows File Server with another one. It’s collapsing a stack of separate purchases (file storage, backup software, DR replicas, ransomware tools, VPN, WAN acceleration) into a single platform.

Effortless on-demand scale

Effortless on-demand scale

Consolidate every site into one global file system, backed by infinitely scalable cloud object storage. No per-volume limits. No DFS quirks. No capacity planning at every branch.

Built-in backup

Built-in backup

Continuous File Versioning® provides immutable recovery points every few minutes with unlimited retention. The “sorry, your changes didn’t get backed up” conversation simply ends.

Ransomware protection

Ransomware protection

Real-time detection of known and zero-day attacks at every edge. Mitigation policies halt spread. One-click restore brings back only the infected files, not the whole server.

Multi-site collaboration

Multi-site collaboration

Same high-performance shares everywhere. Intelligent sync keeps users on the latest version. Global File Lock® eliminates the version conflicts DFS-R quietly creates.

Any cloud, your choice

Any cloud, your choice

Azure, AWS, Google Cloud, Oracle, or private cloud, single-cloud or multi-cloud, for vendor strategy, regional performance, or data sovereignty. The platform doesn’t dictate your cloud.

Remote access without VPN

Remote access without VPN

Hybrid and remote workers get fast file access from anywhere through Advanced Web Access. No VPN tunnel, no WAN acceleration appliance, no support ticket every Monday morning.

Customer proof · Pernod Ricard

We installed Nasuni. We did the data migration, and there’s no need to take care of the file system anymore. We have less patching. We have less work than on the traditional Windows File System. It runs and you don’t have to worry about it.

How Nasuni handles what Windows File Servers can’t.

What follows is the operational reality across the dimensions that actually matter when a file server outage hits at 3 AM, a ransomware alert lights up a branch, or finance asks why three OPEX lines exist for one workload.

Users won’t notice the migration. That’s the point.

Drive mappings stay the same. Applications keep working. Nasuni and our partners have moved petabytes of Windows file data into production without disrupting users, across hundreds of branch sites in a single rollout when needed.

1

Inventory & assessment

Nasuni maps every Windows File Server you’re running, the data it holds, and the access patterns behind it. You get a written migration plan and TCO comparison before any commitment.

2

Parallel deployment

Nasuni Edge VMs spin up alongside your existing servers. No rip-and-replace, no procurement cycle, no rack visits. Drive mappings and SMB paths stay identical.

3

Cutover with no downtime

Files migrate in the background. Users keep working. When the cutover happens, applications keep working too. Your Windows File Servers become a decommissioning exercise, not a workload.
